TLP172A
Unit: mm
The Toshiba TLP172A consists of an infrared emitting diode optically coupled to a photo-MOSFET in a 4-pin SOP package. This photorelay has higher output current rating than phototransistor-type photocoupler; hence, it is suitable for use as On/Off control for high current.
• 4-pin SOP (2.54SOP4): Height = 2.1 mm, pitch = 2.54 mm • Normally open (1-form-A) device • Peak off-state voltage: 60 V (min) • Trigger LED current: 3 mA (max) • On-state current: 400 mA (max) • On-state resistance: 2 Ω (max) • Isolation voltage: 1500 Vrms (min) • UL-recognized: UL 1557, File No.E67349 • cUL-recognized: CSA Component Acceptance Service No.5A
File No.E67349 • VDE-approved: EN 60747-5-5 (Note 1)
Note 1: When a VDE approved type is needed, please designate the Option(V4).

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
Note 1: LED pins are shorted together. Detector pins are also shorted together.
